How to Turn On Light in Revit?

Understanding Lighting in Revit

To effectively turn on lights in Revit, it is crucial to have a basic understanding of how Revit manages lighting and renders scenes. Revit provides different lighting options, including both natural light sources from the sun and artificial lighting from fixtures. Knowing how to manipulate these options ensures your models are well-lit and accurately represent your design intentions.

Selecting the Right Lighting Scheme

Before activating lights in your project, confirm that you have chosen an appropriate lighting scheme for your specific view. Here are the steps to select a lighting scheme:

1. Navigate to the View tab in the ribbon.
2. Click on the Lighting Scheme drop-down menu, typically found in the Visibility/Graphics options.
3. Choose an option that accommodates artificial light, such as ‘Interior: Lighting’ or ‘Interior: Sun and Artificial Lighting.’
4. Ensure that your current view reflects the lighting scheme change by refreshing or re-rendering the view.

Choosing the wrong scheme, such as ‘Interior: Sun only,’ will prevent artificial lights from being rendered.

How to Add Lights in Revit

To enhance your project with artificial lighting, follow these steps to add lighting fixtures:

1. Open the Project: Begin by opening your Revit project where you want to install the lights.
2. Access the Lighting Fixtures: Go to the ‘Architecture’ tab on the ribbon.
3. Select Lighting Fixture: Under the ‘Electrical’ panel, click on ‘Lighting Fixture.’ This will open the loaded lighting fixtures from the family browser.
4. Choose the Fixture: Scroll through the available families and select the desired light fixture. If none are loaded, you may need to load a family from the library.
5. Place the Fixture: Click within your drawing area to place the lighting fixture. Adjust its position as needed.

Make sure the fixtures are placed appropriately to illuminate the intended areas within your design.

Adjusting Light Intensity

Once lights are added to your project, you may want to modify their brightness. Adjusting light intensity can be done easily:

1. Select the Fixture: Click on the lighting fixture you wish to modify within your project view.
2. Open Type Properties: In the Modify | Lighting Fixtures tab, locate the Type Properties panel and click on it.
3. Duplicate the Type: If you wish to create a new type with altered properties, use the ‘Duplicate’ feature and name your new type.
4. Modify the Initial Intensity: In the Type Properties dialog, find the parameter labeled ‘Initial Intensity.’ Click on the value field next to it to enter a new intensity level.
5. Confirm Changes: Click ‘OK’ on the dialog to apply your changes.

This allows you to customize the brightness of each fixture, ensuring the rendering reflects your desired aesthetic.

Checking Lighting Visibility in Views

To ensure that your added lights are visible in the rendered views, check the following:

1. Visibility/Graphics Settings: Press ‘VG’ or navigate to the View tab, and select ‘Visibility/Graphics.’ Make sure the ‘Lighting Fixtures’ category is checked.
2. Rendering Settings: Go to the Render settings in the view menu, and ensure that artificial lights are set to be included in the rendering process.
3. Re-render the Scene: After making changes to the visibility or lighting settings, re-render your view to see the effects take place.

Proper visibility ensures that all lights contribute to the overall illumination of your design.

FAQs

1. Why are my lights not appearing in the render?

Ensure that you have selected the correct lighting scheme and that all lighting fixtures are properly placed and visible in the active view settings.

2. Can I adjust light intensity after placing the fixture?

Yes, you can adjust the intensity of light fixtures at any time within the Type Properties by modifying the Initial Intensity parameter.

3. What should I do if a loaded light fixture is not visible in the drawing area?

Check that the fixture is not hidden in the visibility settings and confirm that you are in a view that supports rendering lights, such as an interior view.
